Pipe inner wall spraying spray lance

The utility model relates to a pipe inner wall spraying spray lance, it is including setting up supporting mechanism and the spraying mechanism in the frame, the supporting mechanism is located the downside, corresponds with spraying mechanism is vertical, spraying mechanism passes through the cylinder setting at the frame top, the utility model discloses a radially is putting to slope setting to same in a plurality of wind gaps, the air current forms the air current of axial spiral in the work piece, because the outside part of the tiny particle molecule of the effect of centrifugal force lacquer is loose, the reattachment is on the pipe wall, the air current can reduce the volume of adhering to of nozzle department like this, to coat with lacquer the particle carries at axial distal end, the spraying that the inside pipe wall can be more even like this, will there be the discharge of wind gap entering in the wind -guiding hole, it avoids environmental pollution to be siphoned away exhaust gas to handle by t
